* kvm-arm64/parallel-access-faults:
: Parallel stage-2 access fault handling
:
: The parallel faults changes that went in to 6.2 covered most stage-2
: aborts, with the exception of stage-2 access faults. Building on top of
: the new infrastructure, this series adds support for handling access
: faults (i.e. updating the access flag) in parallel.
:
: This is expected to provide a performance uplift for cores that do not
: implement FEAT_HAFDBS, such as those from the fruit company.
KVM: arm64: Condition HW AF updates on config option
KVM: arm64: Handle access faults behind the read lock
KVM: arm64: Don't serialize if the access flag isn't set
KVM: arm64: Return EAGAIN for invalid PTE in attr walker
KVM: arm64: Ignore EAGAIN for walks outside of a fault
KVM: arm64: Use KVM's pte type/helpers in handle_access_fault()
